Entanglement Harvesting and Divergences in Unruh-DeWitt Detector Pairs
(University of Waterloo, 2017-08-28)We analyze correlations between pairs of detectors quadratically coupled to real and complex scalar bosonic fields in 3+1 dimensions. This is a first step toward studying the entanglement structure of the fermionic ... -
Entanglement in Non-inertial Frames
(University of Waterloo, 2008-09-19)This thesis considers entanglement, an important resource for quantum information processing tasks, while taking into account the theory of relativity. Not only is this a more complete description of quantum information, ... -
Entanglement quantification and quantum benchmarking of optical communication devices
(University of Waterloo, 2012-04-27)In this thesis, we develop a number of operational tests and tools for benchmarking the quantum nature of optical quantum communication devices. Using the laws of quantum physics, ideal quantum devices can fundamentally ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ... -
Entropically Driven Formation of Hierarchically Ordered Nanocomposites
(American Physical Society, 2002)Using theoretical models, we undertake the first investigation into the rich behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of coupled self-assembly ... -
Equilibrium Phase Behaviour of Liquid Crystalline Polymer Brushes
(University of Waterloo, 2019-08-29)Using self-consistent field theory of worm-like chains with Maier-Saupe interactions we study the equilibrium phase behaviour of liquid crystalline (LC) polymer brushes. In a good solvent the brush extends out normal to ... -
Error characterization and quantum control benchmarking in liquid state NMR using quantum information processing techniques
(University of Waterloo, 2008-09-12)Quantum information processing has been the subject of countless discoveries since the early 1990's. It is believed to be the way of the future for computation: using quantum systems permits one to perform computation ... -
Estimating and Mitigating Effects of Space Radiation Damage in Single-Photon Avalanche Diodes
(University of Waterloo, 2022-02-01)Satellite-based quantum key distribution necessitates practical and robust detectors capable of withstanding the harsh environment of space. Single-photon avalanche diodes (SPADs) have been shown to fulfill the required ... -
An estimation theoretic approach to quantum realizability problems
(University of Waterloo, 2023-09-27)This thesis seeks to develop a general method for solving so-called quantum realizability problems, which are questions of the following form: under which conditions does there exist a quantum state exhibiting a given ... -
Evaluating Characteristic Parameters for Carbon Dioxide in the Sanchez−Lacombe Equation of State
(American Chemical Society, 2017)For many different pure substances, large numbers of competing characteristic parameter sets exist in the literature for the Sanchez−Lacombe equation of state. This is due in part to differing research requirements or ... -
Evaluation and Comparison of Two Novel Non-Platinum-Based Antitumor Agents on Pancreatic Cancer and Triple-Negative Breast Cancer
(University of Waterloo, 2022-10-03)Cancer is one of the leading causes threatening human life. People suffering from pancreatic cancer and triple-negative breast cancer (TNBC) have particularly low survival rate among all cancer types. The novel non-platinum ... -
Evaluation and Correlation of Morphological, Blood Flow and Physiological Retinal Changes in a Rat Model of Glaucoma with a Combined Optical Coherence Tomography and Electroretinography System
(University of Waterloo, 2017-08-29)Glaucoma is a chronic disease associated with progressive dysfunction of the retinal ganglion cells (RGC), reduction of the retinal blood flow, thinning of the retinal nerve fiber layer (RNFL) and deformation of the optical ... -
The Evolution of Dark Matter Haloes in Mergers
(University of Waterloo, 2019-08-22)In the standard Λ-cold dark matter (ΛCDM) cosmological model, the present-day universe contains dominant components of dark energy (Λ) and cold dark matter (CDM). Fluctuations in the initial distribution of dark matter ... -
The Evolution of Subhalo Orbits in Galaxy Clusters
(University of Waterloo, 2023-10-23)Galaxies and their dark matter structures are commonly found within larger-scale structures called galaxy clusters. These clusters exhibit unique conditions to their constituent galaxies, as they have an elevated density ... -
Exact Results in Gauge Theories

Exact Results in Supersymmetric Gauge Theory
(University of Waterloo, 2016-08-30)Exact results are a key component for understanding any physical theory. Unfortunately in the context of quantum field theory (QFT) they are in general impossible to obtain, and we need some sort of approximations. However ... -
Exact Solutions and Black Hole Stability in Higher Dimensional Supergravity Theories
